I made a new bracket out of 1/4 aluminum that bolts to the block an then bolted the 850 bracket to that with some custom made spacers and a small mod to the 850 bracket. I made two different ones. One for a/c and one without a/c. One consideration is the intake tube, weather its NA or turbo, will have to be modified to fit around the ps pump. If someone wanted to get all of the accessories I could put together the brackets, spacers, fittings, modified pulleys and directions for a pretty good price either with or without a/c. Ill start pricing some of the items out and put a post in the for sale forum.

I dont have an air intake so I don't know if it interferes or not just a concern. i'm putting together a second one right now. I will post some photos of the assembly and more photos of the parts. my car is a b23 and a timing cover wont fit. you have to trim the crank cover where it comes around the timing gear on the crank so the new pulley clears. I have been running this set up for about 3 weeks and I drive about 70 miles a day to work. As far as pushing it my car is the slowest Volvo in the world so it hasn't been pushed but i haven't had any problems.

Ok I figured out a solution to increase the belt contact with the crank pulley. I'm going try to get a prototype this weekend along with some photo. I'm also going to install the non-ac version and take some photos of that too.

Knuth also cites a letter sent to him by Dijkstra, in which the latter adds some nuance to this earlier statements: "Please don't fall into the trap of believing that I am terribly dogmatical about [the go to statement]. I have the uncomfortable feeling that others are making a religion out of it, as if the conceptual problems of programming could be solved by a single trick, by a simple form of coding discipline!"

Im not sure of the years but I remember installing the one way type pulleys with the clutches on 5 cyl cars when I was working at the dealer. This was done as a fix for strange noise/vibration that later cars didn't have a problem with because they came with the clutch type pulleys from the factory 2000+.
That said, the clutch pulley can be removed and a normal pulley from and an older car with the same type alt. can be installed so the alternator will rotate backwards.

Got to be careful if you consider rotating it backwards, all 2000+ alternators I see have 'free-wheeling' if it's rotated backwards, there's a one-way bearing built into the pulley.

If the belt routing is modified similar to my routing (obviously allowing for the WP on the left of motor), the later (00'-) alt is not running backwards, it's designed to run CCW (on the inside of the belt), hence the dual-ribbed belt.

if you use a tensioner AND an idler, you can run it CW, but the belt is longer & now you have an extra pulley to worry about
